I find them slippery sometimes, even with the ridges on the right one and sparked me to ask, since there are mods for everything else, has anyone seen any for the paddles? Like rubber grps or something like that.

 

I have not heard of any, but I am working on a few different things (paddle shifters included). I am aiming realy high on crafsmanship and design. My best man and I are getting together in our friends machine shop in a couple of weeks to try few things. I hope manufacturing cost does not kill us. That is why we are trying to do it in a friends owned shop and not just first machine shop around the corner.
If it all goes well, fitfreak community will be the first to sample it.
